[ros-users] rosserial and custom message: cannot load package error

[Adam Stambler]

You are right.  I jumped the gun and didn't read the rest of your message.

If it is loading in ipython, then it should work.

Anyway, I am not sure what the problem is right now.  Could you ask this
question on answers.ros.org.  We can debug this there without polluting
people's inbox.

Regards,
Adam
